What Is 2020 Aluminum Extrusion?<\/h2>\n

2020 aluminum extrusion is a 20mm × 20mm T-slot structural aluminum profile designed for modular frame assembly without welding. The number “2020” denotes its nominal cross-section: 20mm wide by 20mm high. Each face of the profile features a standard T-slot groove, typically 6mm or 6.2mm wide on the slot opening and 10-12mm wide at the inner channel, designed to accept standard T-nuts, bolts, and connecting hardware.<\/p>\n

2020 profiles are most commonly extruded from 6063-T5 aluminum alloy, which offers a good balance of strength, surface finish, and extrudability. The T-slot geometry transforms aluminum extrusion from a simple structural shape into a modular building system \u2014 frames can be assembled, modified, and reused without drilling, welding, or permanent fasteners.<\/p>\n

As one of the most popular T-slot profile sizes, 2020 is widely used for desktop CNC routers, 3D printer frames, laboratory test stands, industrial workbenches, safety guarding, and custom retail displays. Compared with larger T-slot series (3030, 4040, 4545), 2020 profiles are lighter, more economical, and ideally suited for light-to medium-duty framing where compact dimensions and fast assembly are priorities.<\/p>\n

Available 2020 Aluminum Extrusion Profiles<\/h2>\n

Linsy supplies 2020 aluminum extrusion profiles in standard and custom lengths. All profiles are manufactured from 6063-T5 alloy and available with multiple surface finish options.<\/p>\n

Chemical Composition of 6063 Aluminum<\/h3>\n

The 2020 aluminum extrusion profiles are manufactured from 6063 aluminum alloy per GB\/T 3190 \/ ASTM B221 \/ EN 755 standards. 6063 (EN AW-6063 \/ AlMg0.7Si) is a medium-strength Al-Mg-Si alloy optimized for extrusion, offering excellent surface finish after anodizing and good corrosion resistance.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
